openCanvas is a raster graphics software developed and published by PGN Corp.
It was originally released as freeware in 2000,[2] but moved to a shareware model starting with version 2.
Its functions are similar to Adobe Photoshop or Corel Painter.
In 2009, portalgraphics.net ended the sales of the openCanvas English versions.
At the same time, they ended the English version of the portalgraphics website and their online English Customer Services, including PGN User Community.
